his December will mark the 30th anniversary of the signing of the treaty between the Soviet Union and United States on the elimination of intermediate- and shorter-range missiles. This was the start of the process of radically cutting back nuclear arsenals, which was continued with the 1991 and 2010 strategic arms reduction treaties and the agreements reducing tactical nuclear weapons.

The scale of the process launched in 1987 is evidenced by the fact that, as Russia and the United States reported to the Non-Proliferation Treaty Review Conference in 2015, 80 percent of the nuclear weapons accumulated during the Cold War have been decommissioned and destroyed. Another important fact is that, despite the recent serious deterioration in bilateral relations, both sides have been complying with the strategic weapons agreements.

The Intermediate-Range Nuclear Forces (INF) Treaty, however, is now in jeopardy. It has proved to be the most vulnerable link in the system of limiting and reducing weapons of mass destruction. There have been calls on both sides for scrapping the agreement.
